Replacing the Right side knuckle on my 2k Beetle. I used a APWI knuckle from Rock Auto . Got the whole thing together except for the carrier for the disc brake caliper . It appears that the original caliper bolts might be slightly larger than the threads on the new knuckle ! At this point I don't want to force anything , and create more headaches . My 2K was a early production so run I'm wondering if they made some changes along the way on later models ? Also any information on bolts sizes for the carrier would be appreciated or noted deviations from stock on the APWI knuckle. Once again thanks for any info Eldoguy . .
